A statement from California Gov. Jerry
Brown received early Wednesday identified BART
Sgt. Tom Smith, 42, of San Ramon, as the officer shot Tuesday afternoon. Smith,
a detective who's been with the department for 20 years, is survived by his
wife and 6-year-old daughter, Brown said.

"Sergeant Smith's family, friends
and colleagues are in our thoughts as we honor his service during this painful
time," the statement said.

Smith, 42, comes from a law enforcement family, reports CBS San Francisco station KPIX-TV. His wife is a K-9 officer with BART police and
Smith’s two brothers are officers at two other Bay Area agencies. Smith also
behind a young daughter.

The officers – members of BART's detective unit - were conducting a
probation search at an apartment in the East Bay city of Dublin. The governor
said the officers were serving a warrant regarding several robberies on BART property.

The suspect, whose name has not been
released, was not home at the time.

Sgt. J.D. Nelson of the Alameda County
Sheriff's Office, which will investigate the shooting, told the Contra Costa
Times that officers knocked before entering the unlocked apartment with their
guns drawn.

Details about what happened next
haven't been released, but KPIX quotes Nelson as saying the other officer accidentally fired a shot that wounded Smith.

Smith was taken to Eden Medical Center
in Castro Valley, where he died from his injuries.

Television reports showed lines of
officers outside the hospital saluting as their fallen comrade's body, draped
in a large American flag, was loaded into a coroner's van.

"We ask that everyone please give
us a chance to catch our breath" and to grieve, he said.

"The entire BART organization is deeply saddened by this
tragic event, and we ask the public to keep the officer's family in its
thoughts and prayers," Rainey and BART
General Manager Grace Crunican said earlier in a joint statement.

They said they were withholding other
details for now. The name of the officer who fired his gun hasn't been
released.

BART has had its share of
troubles in the past.

Among them was the fatal shooting on
New Year's Day 2009 of Oscar Grant III, an unarmed black BART passenger who had been detained at the
Fruitvale station after reports of a fight.
